摘要： Electric power steering systems and a method for controlling an electric power steering system are provided. The method, for example, includes, but is not limited to, determining, by a controller, a speed of a vehicle based upon data from a sensor, and adjusting, by the controller, a stiffness of an isolator in an electric power steering system via at least one piezoelectric device embedded in the isolator based upon the determined speed of the vehicle.

摘要： A system for calculating an internal load of a component includes an acceleration module, a skew matrix module, a center of gravity calculation module, a mass/inertia module, and an internal load module. The acceleration module may obtain a plurality of acceleration measurements associated with a component, where each acceleration measurement is associated with a response point relative to a center of gravity of the component. The skew matrix module may determine a skew matrix based on the response points. The center of gravity calculation module may calculate a center of gravity response for the component based on the plurality of acceleration measurements and the skew matrix. The mass/inertia module may determine a mass/inertia matrix based on measured mass and inertia values associated with the component. The internal load module may calculate an internal load of the component based on the calculated center of gravity response and the mass/inertia matrix.

摘要： A method and apparatus that cancel component noise are provided. The method includes: detecting a trigger to activate component noise cancellation, in response to detecting the trigger, receiving feedforward information from a component, generating noise cancellation information based on the feedforward information, and outputting a noise cancellation sound according to the noise cancellation information.

摘要： A number of variations may include a product including a variable rate vibration isolator that may include a shape memory material having at least two physical states, wherein each physical state may have a corresponding vibration isolation rate. The vibration isolator may be disposed within and assembly including at least a first part and a voltage source in electrical communication with the shape memory alloy. The product may further include a controller constructed and arranged to pass at least one predetermined current from the voltage source to the shape memory alloy such that the shape memory alloy enters a physical state that dampens vibration of the first part.
